BIOS and CMOS Error Messages and How to Fix Them
โถ BIOS ROM Checksum error
This error appears when there is a problem with the ROM that stores system information.
It occurs when there is an issue while reading the information stored in CMOS. In this case, enter CMOS SETUP and check whether each setting is configured correctly for the current system state.
After completing the settings, select 'SAVE AND EXIT SETUP' to save the changes.
If the system is old, the ROM itself that stores the BIOS information may be damaged. In that case, it is recommended to have it inspected at a motherboard repair shop or service center.
โถ Press [F1] to continue
This message usually appears when the keyboard or mouse is not connected properly.
Please check whether both devices are connected securely to their connectors.
It is also a good idea to check whether the hard disk information is set correctly in CMOS SETUP.
โถ CMOS memory size mismatch
This error occurs when the system cannot properly recognize the memory (RAM).
When new RAM is added, CMOS usually detects it automatically, but in some cases the correct memory size is reflected only after running CMOS SETUP.
Enter CMOS SETUP, check the settings, and then reboot the system.
โถ NO ROM BASIC
This message appears when an error occurs during booting.
It usually occurs when the system cannot boot from drive A. In this case, you need to insert a bootable floppy disk into drive A or change the boot setting to boot from the hard disk drive.
Similar error messages include 'Diskette Boot Failure' and 'Invalid Boot Diskette'.
โถ CMOS display type mismatch
This error occurs when there is a problem with the graphics-related settings in CMOS.
It happens when the graphics type in the 'Video...' item in CMOS SETUP is not set to EGA/VGA.
Since this is the default setting used by most graphics cards, please make sure to check it.
โถ Cache Memory Bad..
This indicates a problem with the cache memory installed on the motherboard.
Cache memory is used to improve system speed, and on some motherboards, this error may appear if the cache memory fails.
In this case, you can replace the cache memory or try setting the cache memory usage option in CMOS SETUP to 'Disable'.
The same symptom may also appear when cache-related settings such as 'Cache Write' are configured incorrectly, so please check those settings as well.

How to Move the Recording Area While Recording
The ability to move the recording area while recording with oCam is very useful when you want to flexibly capture a specific part of the screen in real time. Below is a detailed explanation of how to move the recording area during recording.
To change the recording area while recording is in progress, you can use the border of the recording area. Specifically, even after recording has started in oCam, you can click and drag the border of the recording area window with the mouse to move the recording area to the desired position in real time. This feature can be used simply with mouse control and is intuitive to use without any separate shortcut keys or complicated settings.
For example, when recording gameplay, if a specific part of the screen moves or changes, such as a character's position or a certain UI element, you can drag the border to adjust the recording area in real time and capture the scene you want without missing it. This method is especially useful when recording dynamic content, helping the user respond quickly and continue tracking the necessary screen area.
When moving the recording area, you need to click and drag the border accurately. If you move it too quickly, it may shift to an unintended position, so it is best to control it smoothly and precisely. By using this feature, you can perform more flexible and efficient recording with oCam.
